Team 5 hour 2

  1. 1. How would it affect us?
  2. 2. What caused it?  What scientists detected was a tear in the African plate. That allows heat from Earth’s mantle layer melt the rock of the African plate. The plate build’s up pressure and causes explosive eruptions. Mt. Vesuvius has had a 20 year eruption cycle. But the last serious eruption was in 1947.
  3. 3. What effects did it have on society?  Most people died in a statue form. The air burned their lungs and contracted and quickly turned in to statues, that are still preserved today. An estimated 20,000 people died.
  4. 4. How far did it affect?  13 miles away did lava and ash spray all the way to Herculaneum and a little near Naples. It destroyed all of their properties and buildings.
  5. 5. How did society recover?  Pompeii was slowly recovering from a major earthquake that rocked the city in February of A.D. 62. The shallow quake of Pompeii has now been turned into a tourist site for everyone.
  6. 6. Before and After Pompeii Volcano
  7. 7. Pompeii Volcano
  8. 8. What caused it?  A series of earthquakes that lasted over two weeks caused Mount Pinatubo to erupt. The eruption occurred on June 15, 1991 and it was considered to be the largest volcanic eruption on the 20th century. The effects of the eruption were felt worldwide.
  9. 9. What effects did it have on society?  847 People Killed - 300 from collapsing roofs , 100     from the mud flows known as lahars, the rest from disease in the evacuation centers including measles. •650,000 workers lost jobs •$700 Million Damages •1.2million people lost homes Electricity went off, water was contaminated, road links were destroyed, and telephone links were cut.
  10. 10. How far did it affect?  On March 15, 1991, a succession of earthquakes was felt by villagers on the north-western side of the volcano. Further earthquakes of increasing intensity were felt over the next two weeks, and it became clear some kind of volcanic activity was imminent. On April 2, the volcano awoke, with prelatic eruptions occurring near the summit along a 1.5 km long fissure. Over the next few weeks, small eruptions continued, dusting the surrounding areas with ash. Seismographs recorded hundreds of small earthquakes every day.
  11. 11. How did society recover?  Two decades after the eruption of Mount Pinatubo, the Aetas remain in need of help. They started rebuilding their buildings. The affect still remains today.
  12. 12. Before the Eruption After the Eruption
  13. 13. How could it happen?  A volcano is a week spot in the crust where molten material or magma reaches the surface. Magma is a mixture of rock-forming substances, gases, and water from the mantle. When magma reaches the surface it turns to lava and spews out.
  14. 14. What effects would it have on society?  Some of the effects are good and bad. The bad would be houses, buildings, roads, and fields would be covered with ash and burned down. Lots of people would die because if you breathe in the ash, smoke, and if lava consumes you of any of your body.
  15. 15. How far would it affect?  The effect of an eruption, would effect nearby cities but nothing to bad. Atmospheric conditions may carry ash away from the city or top a graphic may direct lahars and pyroclastic flows to unpopulated areas.
  16. 16. What recommendations would you give for recovery?  Sweep up as much ash as possible. Have people pick up debris, and rebuild houses and building, and help each other out.
